Application July 2, 1943, Serial No. 493,190

This invention relates to new and useful improvements in sheet metal siding for buildings and the like, and it is among the objects thereof to provide prefabricated sheets shaped on opposite edges for interlocking adjacent sheets. The interlocking edges of the sheets are shaped to structural form to provide rigidity to the sheet and strength at thejoint.

Another object of the invention is the provision of prefabricated side wall sheets with interlocking joints of a shape to interact with a combined interlock and anchor member.

We are aware that sheet siding for buildings having interlock joints have been heretofore proposed and also various forms of anchorages for mounting the sheet siding to the building struts have been suggested. Such structures do not facilitate assembly to the supporting members because in most instances they require either telescoping of the interacting sheet edges forming the joint or they require insertion of the anchorage or interlock member at one end of the joint from where it is slid along to the point of anchorage. In accordance with our invention, the sheets are assembled on the supports by merely overlapping them and subjecting them to lateral displacement whereby the sheets become interlocked and the anchorage, which is an L-shaped strap, is inserted at any point in the joint and interlocked with the interacting sheet metal members by simply turning the anchor strap 90. The

strap may then be secured to the support to,

secure the sheets firmly in place.

The invention will become more apparent from a consideration of the accompanying drawing constituting a part hereof in which like reference characters designate like parts and in which:

Fig. 1 is a view in perspective of sheet metal siding embodying the principles of this invention;

Fig. 2 a similar view of a pair of the sheets shown in Fig. 1 in position for assembly;

Fig. 3 a view in perspective of a plurality of the sheets assembled in interlocking engagement and anchored to a building strut; and

Figs. 4 and 5 top plan and side elevational views respectively of an anchorage member for the sheet metal siding.

With reference to the several figures of the drawing, the structure therein illustrated comprises a sheet of metal I of suitable gauge and size having a turned-over end 2 and having the opposite edge of inverted trough shape with sloping walls 3 and I, the wall 4 being turned under flange I.

In Fig. 2 apair of the sheets of Fig. 1 are shown with the inverted trough-shaped member that is generally designated by the numeral 6 placed upon the flat surface of the adjacent sheet.

This might be termed an exploded view of the joint. When the sheets are moved laterally away from each other, the in-turned end 2 of one sheet will interact or overlap the tongue 5 of the adjacent sheet as shown in Fig. 3.

When thus assembled the sheets are interlocked against lateral displacement in one direction and are then locked by an anchor strap generally designated by the numeral I shown in Figs. 4 and 5 having a shank 8 and a leg 9, perforations l0 being provided to secure the strap I to a building support ll,

- As shown in the joint on the lefthand side of Fig. 3, the anchor is inserted edgewise in the joint and is then turned flatwise or 90, in which position the leg 9 substantially fills the space between the in-turned flange 2 of one sheet and the trough element 6 of the other sheet to securely interlock the sheets against lateral displacement in any direction. The strap I is then fastened to the support I I as shown, thereby securing the sheet siding to the building wall.

As will be readily understood from the foregoing description of our invention, the sheet siding members are not telescoped in assembly, and the anchorage member need not be inserted from the end, but may be inserted at any position along the joint before it is turned to eflfect interlocking engagement with the sheets.

By construction of sheet siding joints and anchorage member facilitates the assembly of the siding on building walls or on struts to form building walls and the shape of the structure is such as to form a strong and rigid wall when assembled.

Although one embodiment of the invention has been herein illustrated and described, it will be evident to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth. a

We claim:

1. Sheet metal siding for building structures comprising a plurality of sheets, each shaped to represent a strip of 'weatherboard siding, having an inverted trough-shaped edge terminating in a tongue bent inwardly to lie in a plane with the body of the strip and having its other edge bent back on jitself to interact with the tongue wardly to extend in the plane of the sheet to constitute a tongue, the other edge of the sheet being bent back on itself form ahairpin loop for receiving the tongue 0 a. similarly formed sheet and anchor straps for mounting said sheets on a building structure, said straps being L- shaped with the shank extending into the trough of the sheets and the foot engaging the loop of the sheets to substantially fill the joints in a transverse direction to interlock the assembled 10 sheet against displacement.
